GMS: Making The Right Things Happen – Correctly and Promptly


General & Mechanical Services (GMS) has been working with our commercial customers to improve the resiliency and reliability of their mission critical infrastructure since 1996. GMS combines our industry knowledge and high quality service to offer a broad range of solutions and services to our customers nationwide.

In a commercial building, a properly designed, installed and maintained HVAC solution can help you to save energy, cut absenteeism and improve productivity. For most commercial buildings the mechanical infrastructure is quite literally the heart of the operation and you need a reliable and knowledgeable team to repair, maintain and upgrade equipment—when you need it.

GMS provides a one-stop-shop for mechanical solutions, including HVAC, in commercial buildings and facilities including:

  • Central plant / mission critical infrastructure installation and service, including chillers, boilers, cooling towers, etc.
  • Regular commercial HVAC and mechanical infrastructure service & maintenance
  • Data center HVAC solutions, service & maintenance
  • Electrical switchgear, transformers and generator sets and HVAC piping
  • Cooling, heating, power and water equipment rental
  • Welding repairs with National Board “R” stamp certification

So, whether you’re a hotel chain that needs a comprehensive maintenance plan to cover your commercial HVAC service in single or multiple locations; or a manufacturing plant in need of a new cooling tower, GMS can design, build, install and maintain a solution to meet your needs.
